CHANGES IN THE ELEVATION OF LAND ROUND 
THE BALTIC. 
“ The Swedish Academy recently published (“ Nature,” Dec. 18, 
1884) observations made during the last 134 years, whose result 
is that the Swedish coast has been steadily rising, while that on 
the southern fringe of that sea has been falling, the zero line 
passing from the Schleswig-Holstein coast through Bornholm 
and Zbland. The northern part of Sweden has risen about 
y feet.” n 
In “ On some Properties of the Earth ” (1880, p. 376) I said— 
“ But this oscillation will be accompanied by local changes in 
the volume of the envelope of the earth,” &c., “ and by a local 
gradual rising and sinking of continents and seas.” 
b “ I presume that the greatest local elevation and depression, 
within the 595 years period, in the neighbourhood of the mean 
points and lines (e.g., the Finnian North Cape, and on the same 
meridian near the Antarctic circle), amounts in both senses, in 
rising and falling, to 26 feet, or to 13 feet each way together to 
the 1%- 595 part of the mean depth of the sea.” With a uniform 
rise this would be 6'5 feet in 149 years.

THE BALANCE OF NATURE. 
Since game preserving has been almost abandoned in Ireland, 
it is said that birds of prey have wonderfully increased in num- 
bers and boldness. Kites were common and a died as scavengers
